Python SymPy Permutation.commutator()方法

Permutation.commutator() : commutator()是一个Sympy Python库函数，返回分区的换元。假设’a’和’b’是’C’的一部分，那么a和b的换向器是’C’的标识，如果a和b换向，即ab == ba。

语法 : sympy.combinatorics.permutations.Permutation.commutator()

返回 :
分区的换向器

代码#1：换向器()示例

# Python code explaining
# SymPy.Permutation.commutator()
  
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
  
# Using from sympy.combinatorics.permutations.Permutation.commutator() method 
  
# creating Permutation
a = Permutation([2, 0, 3, 1, 5, 4])
  
b = Permutation([1, 3, 5, 4, 2, 0])
  
  
print ("Permutation a - commutator form : ", a.commutator(b))
print ("Permutation b - commutator form : ", b.commutator(a))

输出 :

Permutation a – commutator form : Permutation([3, 1, 2, 5, 4, 0])
Permutation b – commutator form : Permutation([5, 1, 2, 0, 4, 3])
